' Specification of Letters Patent.

Patented May 23, 191s.

Application filed June 10,1914. Serial No. 844,183.

To all whom it may concern:

Be it known that I, DANmL L. GRosBrE, a citizen of the United States,residing at Sacramento, in the county of Sacramento and State ofCalifornia, have invented certain new and useful Improvements inResilient Wheels; and I do declare the following to be a clear, full,and exact description of the same, such as will enable others skilled inthe art to which it appertains to make and use the same, reference beinghad to the accompanying drawings, and to the characters of referencemarked thereon, whichform a part of this application.

. This invention relates to improvements in resilient wheels used todisplace the now v commonly used pneumatic tires, the present inventionembodying certam improvements in details of construction over that wheelshown in my issued Patents, Numbers 1,058,221; 1,043,571; and1,023,416'and dated April 8th, 1913; Nov. 5th, 1912; and April 16th,1912, respectively.

' The present invention embodies certain improvements in the structureof the auxiliary rim and side plates together with the method of fixingthe solid t1re of said aux iliary rim.

A further object of the invention is to.

'of a wheel partly broken out showing my improved structure.

I Fig. 2 is a sectional view taken on a line XX of Fig. 1 the springbeing omitted. Fig. 3 is a sectional view of a fragmentary portion ofthe wheel showing the method of journaling thespring carriers.

Referring now more particularly to the characters of reference on thedrawings, the

' numeral 1 designates the hub of the wheel,

'2, the spokes, and 3, the felly. Secured to the felly 8 is the mainchannel-shaped rim 4 adapted to receive the flush pins orbolts 5. 'Myimproved structure consists in makingthe side plates 6 and the auxiliaryrim 7 7 integral, such rim being then in two parts so that each" sideplate 6 and one side of the rim 7 will be removable as a unit, the samebeing held together when in position on the wheel by cross bolts 8. Theinner edges of the rim sections 7 are milled out, as at 9, andinterposed between the same is a filler washer 10 to prevent frictionand also to make a closed joint to keep dirt or dust from enteringtherethrough.

The outer surface of each of the members 7 7 is mortised out, as at 11,to'receive a rubber base plate 12 vulcanized to which is the solid outertire 13, there, being two of these tires 13 to each wheel, as shown inFig. 2.

The springs 14, which are interposed'between the inner and outer rims,are suitably mounted on carriers15, which carriers are in turn journaledon the pins 5 and 8 in the manner shown in Fig. 3;

Between the flanges of the rim 1 and the inner edges of the side plates6, I have arranged wear strips 6", which may be of fiber or othersuitable material to reduce the frictional wear between the said members4 and 6.

From the foregoing description it will readily be seen that I haveproduced such a device as substantially fulfils the objects of theinvention as set forth herein.

While this specification sets forth in detail the present and preferredconstruction of the device, still in practice, such deviations from suchdetail may be resorted to as do not form a departure from the spirit ofthe invention as defined by the appended claim.

Having thus described my invention what I I claim as new and useful anddesire to secure by Letters Patent is The combination with a wheelhaving a channel-shaped rim, of an auxiliary rim spaced from saidchannel-shaped rim and being formed into two annular parts, each parthaving a component side plate sliding over one of the sides of saidchannel-shaped
